Page "WLS (AM)" Paragraph 12

Changes were made regarding AM frequencies in 1941 as a result of the North American Radio Broadcasting Agreement ; this moved WENR and WLS from 870 kHz to 890 kHz.

In August 1943, NBC was ordered to divest itself of the Blue Network and its stations ; WENR and Blue were sold to Edward J. Noble.

In 1945 the Blue Network would be renamed as the American Broadcasting Company.

The 1931 sale of the station to NBC moved WENR from the Civic Opera House to the Merchandise Mart, NBC's Chicago headquarters.

The station continued on at the Mart until 1952 by becoming NBC's tenant, moving back to the Civic Opera House in that year.

Paul Harvey's Chicago broadcasting career began at WENR.
